Frequently Asked Questions (FAQ)

Q1. How can I open the CSA.jnlp file extension?
A1.
The Cluster Science Archive User Interface is a Java Desktop Application. To run it, you must have Java Web Start installed on your computer.The Java Web Start software is a component of the Java Runtime Environment (JRE), which can be downloaded here.

Q2. Possible Proxy issue
A2.
Java Web Start should automatically retrieve the web browser proxy configuration in order to allow http connections from the Java WebStart application. However, sometimes the configuration of the proxy is handled centrally by for instance a network division through the use of proxy.pac automatic configuration script.

In this case, the normal WebStart process of determining the proxy information may not work.

To solve this problem, start the "Java Control Panel" included as part of the JRE and select the "Network Settings" option. This then provides a similar set of proxy configuration options as that found in the browser. Specifying the proxy.pac script there can solve the connection problem. If it doesn't, contact your IT support.

Q3. On my Mac, why CSA Java web start works correctly with Firefox but not with Safari?
A3.
This is a relatively recent feature of Safari, it now stores the web start as a file in the Downloads folder. In this case, click on the Show downloads icon in your Safari browser (usually located in the top right corner). This should unfold a listing of the recent files downloaded by Safari. In this list, please click on csa.jnlp. This web start access has been tested successfully using Firefox version 25 and Safari 6.0.5 on MacOS 10.8.5.

Q4. On Windows: trouble with Java WebStart and comodo firewall
A4.
When trying to launch the archive interface, Java WebStart may return the error “splash recv failed”. Solution: add Java WebStart to the list of authorized applications in the Comodo Firewall.

Q5. On Windows: data files corrupted
A5.
A default setting must be changed on the WinZip compression utility. The default setting may corrupt data, while data is being unzipped. Solution: Open WinZip Classic. Select Options > Configuration, and click the Miscellaneous tab. Uncheck the 'TAR file smart CR/LF conversion' box. The box will remain unchecked until it is checked again, or WinZip is reinstalled. Unzip and import the data.

Q6. On all platforms: in case of problem, please clean your Java Web Start cache
